Description

【０００１】
【発明の属する技術分野】
本発明は、換気扇の運転／停止及び強弱の切換えを行う換気扇用引紐スイッチ及び引紐スイッチを備えた換気扇に関するものである。
【０００２】
【従来の技術】
運転／停止及び強弱の切換えを引紐スイッチによって行う換気扇の中には、実開平３―１００７３２号公報に示されているように、引紐スイッチの位置を換気扇本体の下部の左右どちらにも取付けることができるようになっているものがある。即ち、図９に示すように引紐スイッチ３０に連動して動く開閉シャッター３１の連結棒３２が換気扇本体３３の風洞の両側に設けられ、左右どちらに引紐スイッチ３０を取付けても引紐スイッチ３０と開閉シャッター３１の連結棒３２とを連結線等で連結できるようになっている。これにより、換気扇の取付け位置が部屋の入隅部等であっても操作し易い側に引紐スイッチ３０を配置でき、取付位置に対する対応性のある換気扇となっている。
【０００３】
開閉シャッターについては電動のものもあり、この場合には図１０に示すように引紐スイッチは設けず、入／切スイッチ３４と強／弱切換スイッチ３５を備えた操作部３６が付けられることが多い。開閉シャッターの電気回路と送風機モーターの電源回路とは入／切スイッチ３４に接続され、入れ操作で開閉シャッターと送風機モーターの双方に給電され、切り操作で開閉シャッターと送風機モーターの双方が断電される構成である。
【０００４】
【発明が解決しようとする課題】
上記したような従来の換気扇において、引紐スイッチ３０の位置を使い易い左右いずれかの位置に変えることができるようにしたものについては、開閉シャッター３１を動かす連結棒３２が左右両方に必要で、製造コストが高くつくうえ、引紐スイッチ３０の位置を変更するには連結棒３２と引紐スイッチ３０との機構的な連結操作が必要であり、連結操作によっては開閉シャッター３１の動作に不具合が生じるといった問題点がある。また、電動式の開閉シヤッターを採用したものでは、開閉シャッターの開閉と強弱切換えとが符合するわけではないので、引紐スイッチといった簡易な操作手段を適用できないため操作部３６が必要となり、コスト的にも施工面でも課題が残るものとなっている。
【０００５】
本発明は、係る従来の換気扇に関する課題を、引紐スイッチの構造に着目して解決しようとするものであり、電動シャッターへの通電と送風機モーターの強弱切換えとを切離して行える換気扇用引紐スイッチの開発を目的とするものであり、他の目的は、引紐スイッチの取付位置を不具合なく簡単にコストをかけずに変更できる換気扇を開発することであり、引紐スイッチの取付位置の変更操作をより簡易なものとすることである。
【０００６】
【課題を解決するための手段】
前記目的を達成するために請求項1の発明は、引紐の一回の引下ろしで所定の角度ずつ共通接点に電気的に繋がった駒が回転し、強運転用接点と弱運転用接点に切換わるロータリ式の換気扇用引紐スイッチについて、その強運転用接点と弱運転用接点のそれぞれの対角上に電気的に常時繋がったシャッター用接点を設ける手段を採用する。
【０００７】
前記目的を達成するために請求項２の発明は、請求項１に係る前記手段における強運転用接点及び弱運転用接点並びにシャッター用接点と、共通接点とに電線を接続するとともにそれらの端を一つのコネクタにコネクタ接続可能に配設する手段を採用する。
【０００８】
前記目的を達成するために請求項３の発明は、引紐スイッチにより強弱運転が切換わり、運転／停止もさせることができる換気扇について、その引紐スイッチと送風機モーター側の電気回路とを接離可能にコネクタで接続する構成とし、引紐スイッチについては換気扇本体の左右いずれにも取付け得るようにし、前記送風機モーター側の電気回路には並列に左右二つのコネクタを配置する手段を採用する。
【０００９】
前記目的を達成するために請求項４の発明は、引紐スイッチにより強弱運転が切換わり、運転／停止もさせることができ、開閉する電動シャッターを備えた換気扇について、その引紐スイッチを、引紐の一回の引下ろしで所定の角度ずつ共通接点に電気的に繋がった駒が回転し、強運転用接点と弱運転用接点に切換わるロータリ式のものとし、強運転用接点と弱運転用接点のそれぞれの対角上に電気的に常時繋がったシャッター用接点を設け、このシャッター用接点を電動シャッターに接続する手段を採用する。
【００１０】
前記目的を達成するために請求項５の発明は、請求項４に係る前記手段における引紐スイッチと送風機モーター側の電気回路及び電動シャッター側の電気回路とを接離可能にコネクタで接続する構成とし、引紐スイッチについては換気扇本体の左右いずれにも取付け得るようにし、送風機モーター側及び電動シャッター側の電気回路には並列に左右二つのコネクタを配置する手段を採用する。
【００１１】
前記目的を達成するために請求項６の発明は、請求項５に係る前記手段における引紐スイッチを、ケース内に収めケースごと換気扇本体に着脱可能に装着できるようにする手段を採用する。
【００１２】
前記目的を達成するために請求項７の発明は、請求項５又は請求項６のいずれかに係る前記手段における換気扇本体に、引紐スイッチ側のコネクタを着脱可能に装着する取付板を設ける手段を採用する。
【００１３】
【発明の実施の形態】
図１〜図８によって示す本実施の形態は、電気系統としては電動シャッター１と送風機と引紐スイッチ２で構成された換気扇に関するものである。この換気扇は、両端の開放した風洞３に電動シャッター１と送風機と引紐スイッチ２が設けられて換気扇本体４が構成されている。換気扇本体４の前面には図１に示すようにフランジ５が設けられ、このフランジ５の外側を囲むように通風可能なオリフィス（図示しない）が前面に着脱可能に装着される。
【００１４】
風洞３内には図２に示すように送風機モーター６が取付脚７よりその中心線上に取付けられ、その回転軸に羽根車８が装着されて送風機が構成されている。羽根車８は、送風機モーター６により風洞３の一方の開口部において回転し、風洞３に前面側から背面側に向かう換気流を形成する。電動シャッター１は、風洞３の背面側の開口部を開閉する複数のブレードと、これらのブレードを一括して回動させ開閉動させる連結部材と、連結部材を動かす駆動手段としてのギヤードモーター９とから構成され、ギヤードモーター９への通電によって風洞３の背面側の開口部を開放し、断電によって風洞３の背面側の開口部を閉止する。
【００１５】
引紐スイッチ２は、風洞３のフランジ５の下部一側に取付けられ、引紐の引下ろし操作により送風機モーター６への通断電と強／弱切換え及びギヤードモーター９への通断電を行う（図１及び図７参照）。引紐スイッチ２の本体は、絶縁ケース１０に収められ、絶縁ケース１０とともに本体に設けられた掛止構造１１とネジ１２によって図１，図８に示すように風洞３のフランジ５の下部の左右いずれにも取付けることができるようになっている。
【００１６】
引紐スイッチ２の構造は、図４及び図７に示すように引紐の一回の引下ろしで所定の角度（本実施の形態では６０度）ずつ共通接点に電気的に繋がったバネ付勢された駒１３が一方向に回転し、開放接点から強運転用接点１４、弱運転用接点１５に切換わるロータリ式であり、強運転用接点１４と弱運転用接点１５のそれぞれの対角上にそれぞれシャッター用接点１６が設けられている。シャッター用接点１６は、常時電気的な接続状態にあり、強運転用接点１４と弱運転用接点１５との間を駒１３の共通接点が動いてもシャッター用接点１６間の通電状態は維持される。
【００１７】
引紐スイッチ２の強運転用接点１４及び弱運転用接点１５並びにシャッター用接点１６と、共通接点とには図３に示すようにそれぞれ電線１７が接続され、それらの端は一つのコネクタ１８にコネクタ接続可能に纏められている。このコネクタ１８に送風機側の強ノッチ及び弱ノッチの電気回路２０，２１と、電動シャッター１側の電気回路２２の端が一纏めにされたコネクタ２３がコネクタ接続されている。送風機側の強ノッチ及び弱ノッチの電気回路２０，２１と、電動シャッター１側の電気回路２２の端が一纏めにされたコネクタ２３は、並列に二つ設けられており、一つは風洞３の下部右側に、もう一つは左側に配索され、換気扇本体４のフランジ５に、切起こし又は別部品で構成された取付板１９に係脱可能に装着され、引紐スイッチ２の取付位置に合ったコネクタ２３が、引紐スイッチ２のコネクタ１８に接続される。
【００１８】
この換気扇では、引紐スイッチ２の位置を右側から左側、左側から右側に機構部の操作なしに単なるコネクタ１８，２３の接続操作のみで簡単に変えることができ、コネクタ接続であるので誤配線も起こらない。そして、引紐スイッチ２が強運転用接点１４と弱運転用接点１５のそれぞれの対角上に常時電気的な接続状態にあるシャッター用接点１６が設けられた構成であるため、引紐操作により強／弱を切換える際にギヤードモーター９への通電が絶たれ電動シャッター１の動作に不具合が生じるようなこともなく、安定なシャッター動作が実現する。この引紐スイッチ２によれば操作部を設ける必要もなく電動シャッター１を送風機モーター６と協調させて動かすことができ、施工性のよい換気扇が低コストで得られる。電気回路２０，２１，２２側のコネクタ２３は取付板１９で支持されているため、コネクタ接続の接続切離し操作はし易い。さらに引紐スイッチ２の充電部は絶縁ケース１０で覆われ、位置変更時でも絶縁ケース１０ごと引紐スイッチ２を扱うため変更作業はいたって平易である。
【００１９】
【発明の効果】
請求項１の発明によれば、電動シャッターへの通電と送風機モーターの強弱切換えとを切離して行える換気扇用引紐スイッチが得られ、電動シャッター付きの換気扇から操作部を除くことが可能になる。
【００２０】
